[6][7][8] The first season chronicles the life of Yolanda, an attractive and intelligent prisoner, that becomes the mistress of one of the most important drug traffickers of Mexico, Benedictino García, alias "El Centauro".

This relationship, which inside the prison will give much power to Yolanda, will end up becoming her worst nightmare when she manages to be released thanks to Gerardo, a shrewd detective whose last years have been dedicated to the fight against drug trafficking.

The second season tells the story of the Centauro revenge against Yolanda, his former lover and Gerardo, the detective who sought to bring him to justice.

After running away from the authorities for two years, tired of being constantly harassed by the police and the bloody war between his cartel and his rivals, Centauro faked his death along with his second biological son.

Listening to the news of the alleged deaths, Yolanda and her daughter Cristina, as well as Gerardo and his adopted son, Gato, manage to return to Mexico from Canada, where they have lived under the Witness Protection Program.
